TYPEWRITING MACHINE.

Application filed April 28, 1920. Serial No. 37?,189.

To aZZ whom it may concern:

Be it known that 1, Jesse A. B. SMITH, acitizen of the United States, residing in Stamford. in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and is herein disclosed as applied to an Underwood standard typewriting machine of the fan-fold or continuous billing variety shown in the patent to VVernery and Smith,'N0. 1,132,055, dated March 16, 1915.

The work-sheets for such machines are usually in the form of webs fan-folded together, and the forms typed thereon are severed. In such machines it is sometimes desired to utilize narrow webs for the original entry, while the other webs or some of them may be wider to accommodate data not shown upon the original. It is also frequently desirable to slit the web or webs automatically along the fan-folded edges, so that the rhanifolded typed forms are separated laterally from one another.

One feature of the present invention prorides a wide side gaging device for the wide webs, and a side gaging device for the narrow webs, so that the webs will be properly aligned relatively to each other, so that the.

inner forms may be properly'filled out as carbon copies of the outer forms, even-if the different widths of web are drawn from separate sources of supply.

The improvement for severing the webs along their foldsis in the nature of flat sharp-edged tongues or extensions of the usual thin carbon-clip blades projecting at such a special angle that as the web is drawn forward the angular extensions easily slit the fold, which is usually perforated to facili fate such slitting without liability of tearing or fouling the paper. By utilizing carboncl'ip blades of varying lengths according to the width of web used, the sharp thin blades will be found to have comparatively little tendency to shift the webs out of alignment. sidewise relatively to each other .in slitting, if the ga es are properly adjusted.

It has een customary to attach an angularly projecting wire to the end of the carbon blade, and to use the wire for slitting the paper, making it necessary to fit up each blade, often cutting off a piece of the blade to render it of the desired length. In practicing this invention, a supply of the elbowblades of different lengths may be kept in stock and readily applied to any machine as re uired.

ther features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a diagrammatic, fragmentary, perspective view, taken from the rear, of a machine of the kind referred to, many parts being omitted, and showing the two widths of web passing beneath the platen.

Figure 2 is a plan view of the carbon paper-carriage, with the webs threaded therethrough.

Figure 3 is a in Figure 2.

Broad webs. 1, 2 and 3, which may be fanfolded, are drawn from the rear over the cross-bar, not shown, of an extension 4 of the front view of the parts seen typewriter carriage, of which the body is Each clip-bar 6 and 7 is usually provided with a clip 12 pivoted by a pin 13 upon its bar, so that carbon-sheets held by the clips 12 extend between the webs 1 and 2 and the webs 2 and 3.

According to'the present invention, there may also be passed around the )laten 5, and shown herein as outside the we s 1, 2 and 3, a narrow web or a set of webs 14,15, 16 and 17. bon-clip-bars 18, 19 and 20, which carry clips 12 like the clip-bars 6 and 7, and support carbon-sheets 21 between the thicknesses of web 14, 15., 16 and 17. To enable matter typed upon the outer web 17 to be reproduced upon the outer sheet 3 of the broader web, there is also provided a carbonclip-bar 22, carrying a carbon-sheet interposed between the web 3 and the web 14, with theresult that matter typed upon the These webs are threaded between car gaged against the side gage 23' and have their other edges gaged by a side gage 26 adjustably held by a screw clamp 27 to the topifl of the carbon-paper-carriage.

' 0 make sure that the narrow webs do not slip ed over the top of the side gage 26. said gage is provided with an overhanging extension or lip 28, which overhangs the web 14, etc, far enough to insure that the web never escapes from the gage 26. This holds the webs fiat at their folds near where they are'slit. The gage 26 may also be provided with a lower lip 29 to hold the bottom web 1? also in place.

In order to slit or cut the folds 1, 2 and 3 away from each other, their carbon-clip bars 6 and '3 may be provided with angular extensions 30, which lie angularly across the folds between the webs and are preferably fiat and smooth continuations 0' their respective'clip bars, thus holding the webs flat and compact. It is found that the exten sions 30 may advantageously have blunt edges only a little thinner than the body of their clip bar proper, so that in case the folding of the webs has been imperfectly done, the webs will be drawn out flat before they are slit. 7

For severing the narrowwebs 14, 15, 16

l and 17 from each other. their carbon-clipbars are provided with similar extensions 30 having the same function and same position relative to the fold of their respective webs. Thus, the flat blade extensions 30 of-the carbon-clipbars tend to hold the webs flat down in place, and confine the narrow webs properly within the gage 26. For (1011"811'. ience, the carbon-clip-bar- 22 may be provided with an extension 30 like the other carbon-clip-bars, so that one type of said bars will serve for all purposes. Moreover the fact that the bar 22 has the extension 30 overlying the narrow webs helps to confine those Webs in their proper paths. The webs at the printing line upon' the platen 5 will all be positively aligned sidewise, since their side gages 23, 24 and 26 align the edges of the webs, and the portions where they are unslit hold the slit portions aligned at the platen.

The slitting extensions 30 are usually effective when the webs are gaged after the platen 5 is displaced in the usual manner, This is the time when the webs are brought against the usual leading-edge gage, and the carbon-paper-carriage is pushed rcarwardly by its handle 31, which pushes it rearwardly t or carbon may be secured and a thin workweb-cutting blade-portion of the same thicknessas the body-portion, extending obliquely from the. body-portion at the end thereof, and integral therewith, the construction being such that the combined carhon-holding body and work-web-cutting blade may be made by a single stamping operation.
